/**
 * Interface for model transformers that can modify Maven project models at different stages of processing.
 * <p>
 * Model transformers allow plugins and extensions to modify the POM model during the build process.
 * Transformations can be applied at three different stages:
 * <ol>
 *   <li>File model - The raw model as read directly from the file</li>
 *   <li>Raw model - The model after inheritance has been applied</li>

 * </ol>
 * <p>By understanding and properly configuring repositories, developers can control where Maven looks for dependencies, manage access to proprietary artifacts, and optimize the build process to ensure consistency and reliability across projects.
 * </p>

### `response`의 전과 후

*경로 작동*을 받기 전 `request`와 함께 작동할 수 있는 코드를 추가할 수 있습니다.

그리고 `response` 또한 생성된 후 반환되기 전에 코드를 추가 할 수 있습니다.

예를 들어, 요청을 수행하고 응답을 생성하는데 까지 걸린 시간 값을 가지고 있는 `X-Process-Time` 같은 사용자 정의 헤더를 추가할 수 있습니다.

## 다른 미들웨어

미들웨어에 대한 더 많은 정보는 [숙련된 사용자 안내서: 향상된 미들웨어](../advanced/middleware.md){.internal-link target=\_blank}에서 확인할 수 있습니다.

Puedes añadir código que se ejecute con la `request`, antes de que cualquier *path operation* la reciba.

Y también después de que se genere la `response`, antes de devolverla.

Por ejemplo, podrías añadir un custom header `X-Process-Time` que contenga el tiempo en segundos que tomó procesar la request y generar una response:

{* ../../docs_src/middleware/tutorial001.py hl[10,12:13] *}
